Popis: The OBJECTIVE was to compare the immediate results of aortic valve replacement using Perceval S seamless biological prosthesis and aortic valve replacement using Ozaki technique.METHODS AND MATERIALS. From January 2021 to March 2022, 110 patients who underwent aortic valve replacement were analyzed. From this group, patients over 65 years of age with isolated aortic stenosis were selected, who underwent aortic valve replacement using Perceval S seamless biological prosthesis or replacement of aortic valve flaps using S. Ozaki technique. 2 groups were formed from the selected patients. Group 1 included patients over 65 years of age with isolated aortic stenosis (n=20), who underwent replacement of the aortic valve flaps using S. Ozaki technique. Group 2 included patients over 65 years of age with isolated aortic stenosis (n=20) who underwent aortic valve replacement using Perceval S seamless biological prosthesis. RESULTS. There was a decrease in the average and peak pressure gradients on the aortic valve, as well as an increase in both the absolute effective and indexed effective area of the valve opening in the group of patients operated using S. Ozaki technique. CONCLUSION. S. Ozaki surgery and aortic valve replacement using Perceval S seamless biological prosthesis demonstrate satisfactory immediate results of surgical treatment of aortic stenosis. The S. Ozaki technique reduces the likelihood of developing a “prosthesis-patient„ mismatch, but requires a longer time of myocardial ischemia.
